I generally refrain from discussing politics anywhere I’m trying to have a good time. People are really bad at discussing political topics without getting all riled up. It’s exactly the same as religious topics, people get weirdly combatant. I find it much easier to have a good time if you just keep that stuff to yourself as much as possible.
Getting enjoyment from seeing other/young peoples enjoyment diminished is not a dad-thing, it’s just a jerk-thing.
